אולי כדאי לנסות איות אחר או כתיב מלא:
communication content » communication concepts, communication control, communication conflict
using dimensional » one dimensional, high dimensional, n dimensional
state dspaces » state spaces, state space, tate spaces
type dspaces » type spaces, type spares
dspaces » ddspaces
space » dspace

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: communication content using dimensional ((((type dspaces) OR (shape space))) OR (state dspaces))~.
• Adding a wildcard symbol may retrieve word variants: communication content using dimensional ((((type dspaces) or (shape space))) or (state dspaces))*.
